                        Microwave Filter Company, Inc.
                 Announces Receipt of NASDAQ Delisting Notice


East Syracuse, NY - Microwave Filter Company, Inc. (the "Company")
(Symbol:MFCO) received a letter on May 3, 2007 from The Nasdaq Stock Market
informing the Company that the Nasdaq Listing Qualifications Panel has
determined to delist the securities of Microwave Filter Company, Inc. from the
Nasdaq Stock Market, and will suspend trading in the Company's shares
effective with the open of business on Monday, May 7, 2007.

The Company's securities are immediately eligible for quotation in the Pink
Sheets, an electronic quotation service for securities traded over-the-
counter, effective with the open of business on May 7, 2007. Pink Sheets
provides broker-dealers, issuers and investors with electronic and print
products and information services designed to improve the transparency of the
Over-the-Counter (OTC) markets. The products are designed to increase the
efficiency of OTC markets, leading to greater liquidity and investor interest
in OTC securities. Pink Sheets centralized information network is a source of
competitive market maker quotations, historical prices and corporate
information about OTC issues and issuers. Pink Sheets is neither an SEC-
Registered Stock Exchange nor a NASD Broker/Dealer. Investors must contact a
NASD Broker/Dealer to trade in a security quoted on the Pink Sheets. Pink
Sheets LLC is a privately owned company headquartered in New York City. More
information is available at http://www.pinksheets.com.

The Company's common stock may, in the future, also be quoted on the Over-the-
Counter Bulletin Board maintained by the NASD, provided that a market maker in
the common stock files the appropriate application with, and such application
is cleared by, the NASD. We have been in contact with a market maker and they
will be filing a Form 211 with the NASD OTC Compliance Unit in order to quote
our common stock. The Form 211 is the form to initiate quotations in the OTC
Bulletin Board (OTCBB), the "Pink Sheets" or any other comparable quotation
medium pursuant to SEC Rule 15c2-11. We believe that upon approval of the Form
211, our common stock will be able to be quoted on the OTCBB. The OTCBB is a
regulated quotation service that displays real-time quotes, last-sale prices
and volume information in OTC equity securities. An OTC equity security
generally is any equity that is not listed or traded on NASDAQ or a national
securities exchange. OTCBB securities include national, regional and foreign
equity issues, warrants, units, ADRs, and Direct Participation Programs. More
